Help......fun......online!?

What are some fun games that you can download on to your computer. My system: Mac Os X P.S. that means that it has to have a mac version or it is a MAC version. Im a girl, and I love games like sims and other life simulation games It has to be something I can find by going to the internet. Oh and it does not matter the rating I love all games I played Grand theft auto at the age of 9!
For Help......fun......online!? try this:

• if you want free online multiplayer games go to www.mmosite.com.
  www.onrpg.com
  
  i dont know any single player downloadable games since youre using a mac, sorry
  
• Emuparadise.org
  Console and Handheld games available for download for free
  but you didn't hear this from me... lol
  
• I agree that World of Warcraft is the best game you can get for a Mac. That's all I play! Server: Dunemaul, char: Tamin!
  
  Come join the fun :-)
  
  Though I guess it's not an online game in the sense that it's not embedded into a browser. If you're looking for something you can play while at work, then I really can't help out in that department :-(
  
• play world of warcraft its fun. and if you do get into it, my server is muradin if you wish to hang with meh.
